Hello Michel, Pierre also suggested checking the performance of this OSD's device(s) which can be done by running a ceph tell osd.x bench. One think I can think of is how the scrubbing speed of this very OSD could be influenced by mclock sheduling, would the max iops capacity calculated by this OSD during its initialization be significantly lower than other OSDs's. What I would do is check (from this OSD's log) the calculated value for max iops capacity and compare it to other OSDs. Eventually force a recalculation by setting 'ceph config set osd.x osd_mclock_force_run_benchmark_on_init true' and restart this OSD. Also I would: - compare running OSD's mclock values (cephadm shell ceph daemon osd.x config show | grep mclock) to other OSDs's. - compare ceph tell osd.x bench to other OSDs's benchmarks. - compare the rotational status of this OSD's db and data devices to other OSDs, to make sure things are in order. Bests, Frédéric. PS: If mclock is the culprit here, then setting osd_op_queue back to mpq for this only OSD would probably reveal it. Not sure about the implication of having a signel OSD running a different scheduler in the cluster though. ----- Le 22 Mar 24, à 10:11, Michel Jouvin michel.jouvin@ijclab.in2p3.fr a écrit :
Pierre,
Yes, as mentioned in my initial email, I checked the OSD state and found nothing wrong either in the OSD logs or in the system logs (SMART errors).
Thanks for the advice of increasing osd_max_scrubs, I may try it, but I doubt it is a contention problem because it really only affects a fixed set of PGs (no new PGS have a "stucked scrub") and there is a significant scrubbing activity going on continuously (~10K PGs in the cluster).
Again, it is not a problem for me to try to kick out the suspect OSD and see it fixes the issue but as this cluster is pretty simple/low in terms of activity and I see nothing that may explain why we have this situation on a pretty new cluster (9 months, created in Quincy) and not on our 2 other production clusters, much more used, one of them being the backend storage of a significant OpenStack clouds, a cluster created 10 years ago with Infernetis and upgraded since then, a better candidate for this kind of problems! So, I'm happy to contribute to troubleshooting a potential issue in Reef if somebody finds it useful and can help. Else I'll try the approach that worked for Gunnar.
Best regards,
Michel

Hello Michel,
It might be worth mentioning that the next releases of Reef and Quincy should increase the default value of osd_max_scrubs from 1 to 3. See the Reef pull request: https://github.com/ceph/ceph/pull/55173 You could try increasing this configuration setting if you haven't already, but note that it can impact client I/O performance.
Also, if the delays appear to be related to a single OSD, have you checked the health and performance of this device?

Hi,
As I said in my initial message, I'd in mind to do exactly the same as I identified in my initial analysis that all the PGs with this problem where sharing one OSD (but only 20 PGs had the problem over ~200 hosted by the OSD). But as I don't feel I'm in an urgent situation, I was wondering if collecting more information on the problem may have some value and which one... If it helps, I add below the `pg dump` for the 17 PGs still with a "stucked scrub".
I observed the "stucked scrubs" is lowering very slowly. In the last 12 hours, 1 more PG was successfully scrubbed/deep scrubbed. In case it was not clear in my initial message, the lists of PGs with a too old scrub and too old deep scrub are the same.
Without an answer, next week i may consider doing what you did: remove the suspect OSD (instead of just restarting it) and see it unblocks the stucked scrubs.
Best regards,
Michel
